Answer :
Answer:
5.23 moles of C₁₀H₈N₂O₂S₂
Explanation:
In order to find the moles of dipyrithione we need to know its formula:
C₁₀H₈N₂O₂S₂
1 mol of N contains 6.02×10²³ atoms
We need to find out the moles of 6.3×10²⁴ atoms of N
6.3×10²⁴ atoms . 1 mol /6.02×10²³ atoms = 10.4 moles of N
Therefore, we know that 1 mol of dipyrithione has 2 moles of N, so we need to make this rule of three:
2 moles of N are contained in 1 mol of C₁₀H₈N₂O₂S₂
10.4 moles of N must be contained in (10.4 . 1) /2 = 5.23 moles of C₁₀H₈N₂O₂S₂
Answer:
5.2 moles dipyrithione contain 6.3 * 10^24 atoms of nitrogen
Explanation:
Step 1: Data given
Dipyrithione = C10H8N2O2S2
Number of Avogadro = 6.02 * 10^23
Number of nitrogen atoms = 6.3 * 10^24 atoms
Step 2: Calculate moles nitrogen
Moles nitrogen = atoms nitrogen / number of Avogadro
Moles nitrogen = 6.3 * 10^24 / 6.02 * 10^23
Moles nitrogen = 10.47 moles
Step 3: Calculate moles dipyrithione
In 1 mol dipyrithione we 2 moles N
For 10.47 moles N we have 10.47/2 = 5.2 moles dipyrithione
5.2 moles dipyrithione contain 6.3 * 10^24 atoms of nitrogen
